Professor Blight continues his march through the political events of the 1850s. He continues his description of the aftermath of the Kansas-Nebraska Act of 1854, describing the guerilla war that reigned in the territory of Kansas for much of 1856. The lecture continues, describing the caning of Senator Charles Sumner on the floor of the US Senate and the birth of the Republican party. The lecture concludes with the near-victory of Republican candidate John C. Fremont in the presidential election of 1856, and the passage of the Dred Scott decision in 1857.
